Offshore wind – MacGregor perspective

Hywind Scotland Pilot Park ■ 30 MW totally installed

o 5 Floating Wind Turbines o 6 MW each

Statoil Hywind - A challenge on our own “technology home field”

Design Basis - challenges ■ Safe and robust installation and dis-connection

o Without large winches on wind turbine o Without diver intervention

■ Challenging mooring chain dynamics o 20 years lifetime

■ Comply with offshore quality and safety requirements ■ Cost efficient

The road to a solution ■ R&D cooperation with

Statoil ■ Concept study

o Installation methodology o Suitable for ROV

operation ■ Chain fatigue analysis

o Tension and bending (OPB) fatigue in combination

■ Equipment designed to give optimum fatigue life for chain

The solution - When our expertise makes a difference

New mindset – the big difference ■ Offshore oil field

o One vessel, limited number of mooring lines, many rig moves

■ Offshore wind turbine park o Forty or more turbines, possibly 200

mooring lines, minimal mooring line adjustment

This call for a different mind-set o Permanently installed equipment must

be minimal and simple o Tools to be used during installation and

maintenance may be advanced Procedures must allow for using the less

expensive Anchor Handling Vessels (AHV)

Offshore Gangway System

A complete Active Motion Compensated telescopic gangway designed for efficient and safe transfer of personnel to fixed offshore installations.

The gangway feature standard two axis compensation. As an option, pedestal compensation can be delivered.

The gangway is delivered and mounted on a circular pedestal. All main operational functions are all controlled from a spacious fully equipped operator cabin

The gangway can be delivered with MacGregor’s pedestal telescopic elevation system.

The gangway is designed and manufactured according to DNV-ST-0358: 2015 Certification of Offshore Gangways for Personnel Transfer.

Offshore Gangway System

simulation system for virtual product design

A MacGregor in-house developed software system

Background - History 2008 : Started as a lab tool for control systems as PLC testing software

2009 : The result from this project lead to a complete offshore crane training simulator, completely designed and developed in-house by MacGregor

2009-2012 : A proof of success is 3 sales to two external customers, US navy and Kongsberg maritime of total value ca 4mill. NOK

2012-2015 : Implemented new physics engine, 3D engine and UI design system. System used in all projects as engineering, testing and verification tool

Evolution

06 April 2017 16

C•How range of applications Design

New products : Faster testing of concepts Mechanical : Movement / collision testing Calculation of strength : Acceleration / Force Simulation of hydraulic systems : Design verification Control systems : Quality control

Marketing Advertising / Videos Demonstration of functionality Marketing of new products

Safety Testing the system before it is built Testing the system under conditions which is

impossible or of high risk in the real world

Training Improve the quality of our crane operator courses A saleable training tool In-house training

Management Planning tool for marine operations Logging of marine operations with playback option for evaluation and

improvement of future operations ”Black box” This is required equipment in commercial aviation. The simulator can

be used to log all necessary information which is produced during operation of equipment. After an incident the information can be played back in the simulator and recreate the incident. This is useful for finding the cause.

The main parts of C•How

C•How Methods: advanced functionality in the simulator system; enables the possibility to read all data in the system, do calculations and write back in real time.

C•How Graphics: loading and displaying 3D/2D graphics, manipulate the scene in real time, multiple cameras, multiple screens/PCs.

C•How Physics: calculates the physic world of a 3D scene. Motion, collision, forces, deformation.

C•How Server: a common pool of data for the different parts of the system.

C•How Designer: creates 2D user interfaces for all parts of the system.
